Hey guys. I finnaly got that dock but wondering what adapter I have to use ? I mean the small rubber things that came with it, the Fuze will be used with Leather case or silicone case when docked if it's important

I don't have one, but I believe I recall others posting that they use it without any adapter. The Griffin dock came out a while before the Fuze and was discontinued shortly after, so I don't think there is any adapter to fit the Fuze specifically.

I don't use a case with my Fuze. I think I used the grey insert that was meant for the e series players, and it works OK. It does leave a bit of wiggle room on my naked Fuze. Since yours has a case, it might fit perfect. If not, one of the other inserts will likely do the trick.
